摘要： A method and system for wireless communication in a wireless network is provided. One implementation involves a requesting wireless station directionally transmitting a request to a coordinator for access to a communication channel; the request packet includes a field indicating the length of the desired reservation period; and upon successfully receiving the request from the wireless station, the coordinator reserving a channel time period for data transmission by the requesting wireless station, and at least pseudo-omni-directionally broadcasting a packet to all wireless stations in the network indicating the reservation. All other stations refrain from contending the channel during the reserved channel time period.

摘要： A method and system for audio transmission in a wireless communication system which transmits digital video and digital audio in High-Definition Multimedia Interface (HDMI) format. Position information of audio packets within the HDMI frame is obtained. Digital audio information including the position information is transmitted from a data source device to a data sink device via a wireless communication medium.

摘要： A high accuracy clock synchronization mechanism between a sender and a receiver in a communication network achieves time synchronization using broadcast beacons, directly at the PHY/MAC layer of the sender and the receiver, to minimize synchronization delay jitter. This provides a more efficient synchronization method than either NTP or SNTP, because multiple handshaking information exchange is avoided. Further, using beacons avoids the overhead of introducing additional synchronization packets in higher layer synchronization.
